To all 'whom z't may concern:

Be it known that I EUGENE W. VooEL a citizen of the United States, residing at 'Oak' Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bond-VVire Protectors, of which the following is a specification:

My invention relates to devices for supporting and holding in place the wires used for bonding together railroad rails, devices of this class being commonly called bond wire protectors; and the invention has for its object to provide a novel and improved bond wire protector which will be simple, inexpensive to manufacture, readily applied to the angle bar employed for making the joint between the rails to be bonded, and which is so constructed that the part inclosing or bearing upon the wire or wires will come, into contact therewith along a single line only so as to do away with the corrosion of the wires which is incident to the use of bond wire protectors heretofore used. In these devices clips are employed which are bent sheet metal. The result is a certain amount of water collects in the part of the clip inclosing the wire or wires which sooncauses the wire or wires to rust.

The invention is illustrated, in certain preferred forms, in the accompanying drawings wherein Figure 1 is a side elevation of a pair of railroad rails bonded by wires which are supported and held in position on the angle bar by devices constructed in accordance with the invention; Fig. 2, a sectional View on line 22 of Fig. 1 Fig. 3, a detail inverted sectional plan, on an enlarged scale, taken on line 33 of Fig. 1; Fig. 4, a view, in perspective, of the bond wire protector shown in the preceding figures; Fig. 5, a view, similar. to Fig. 1, illustrating a modi lied form of protecting device; Fig. 6, a sec tional view on line (S6 of Fig. 5, and Fig. 7, a view, in perspective, of the protecting device shown in Figs. 5 and 6.

Like characters of reference designate like parts in the several figures of the drawings.

Referring first to Figs. 1 to 4: inclusive, 10 designates apair of railroad rails supported on ties 11 and connected together by the angle bars or splice bars 12 bolted to the rails by bolts 13. The bond wires are designated I l and are secured to the rails which they bond in any suitable manner. The bond wire protector illustrated in these figures consists of an attaching member or plug 15 adapted to be driven into a suitable perforatron 16 drilled in the outside angle bar 12, and of a bond wire supporting member 17 made of a length of wire, preferably of the same diameter as the bond wires 14, one end of which is fitted into a perforation 18 in the outer, end of the plug 15 and the other end of which is bent into the form of a hook 19. hen the plug is driven into the angle'bar the hook 19 surrounds and incloses the bond wires 14, being preferably spread or flattened out by contact with the angle bar. The hook 19 being circular in cross section, bears upon the wires with a line contact only so that there is no possibility of water being trapped or collected between the protecting device and the angle bar as is the case with the protecting devices employing flat clips. For this reason the use of my device does not give rise to the corrosion of the wires which is of such common occurrence when bond wire protectors of the types heretofore in use are employed.

Figs. 5 to 7 inclusive, show a modified form of device in which the wire 17 is fixed at its middle in the plug and is formed at opposite ends with hooks '19; the bond wires 1 1 in this case, being separated and one of them fastened to the upper part of the angle bar and the other to the lower part. The wires 17, 17, as the case may be, are secured to the plugs 15 in any suitable manner, for example, by the galvanizing operation to which the devices are subjected in order to prevent rusting. v

In the claims I have used the term splice bar in a generic sense to designate the element shown as an angle bar which constitutes, or forms a part of, the means for connecting the ends of therails.

I claim:

1. The combination with a splice bar for connecting the ends of adjacent rails of a railroad track, which bar is formed with an aperture, and a bond wire; of a bond wire protector comprising a heavy wire bent into the form of a hook, and a plug having a drive fit in the aperture of the splice bar, which binds said hook against the splice bar so that the hook incloses the bond wire 2. The combination with a splice bar for connecting the ends of adjacent rails of a, railroad track, which bar is formed with an aperture, and a bond wire; of a bond wire protector comprising a plug adapted to be driven into said aperture, and a heavy wire hook device, secured to the outer end of the plug transversely thereof, with the hook portion thereof surrounding-said loond wire and pressed against the splice bar.

3. The combination with a splice bar for connecting the ends of adjacent rails of a railroad track, which bar is formed with an nwaaee aperture, a pair of bond wires connecting said rails; of a bond wire protector comprising a plug adapted to be driven into said aperture, and a heavy wire hook device, extending through the outer end of the plug transversely thereof and formed at'opposite ends with hooks adapted to bear resiliently against the splice bar and to inclose said bond wires. v
